Model for transitional turbulence in a planar shear flow
Santiago J. Benavides, Dwight Barkley
A central obstacle to understanding the route to turbulence in wall-bounded flows is that the flows are composed of complex, highly fluctuating, and strongly nonlinear states. In t…
Wall mode dynamics and transition to chaos in magnetoconvection with a vertical magnetic field
Matthew McCormack, Andrei Teimurazov, Olga Shishkina +1
Quasistatic magnetoconvection of a low Prandtl number fluid ( with a vertical magnetic field is considered in a unit aspect ratio box with no-slip boundaries. A…
Multi-scale invariant solutions in plane Couette flow: a reduced-order model approach
Matthew McCormack, André V. G. Cavalieri, Yongyun Hwang
Plane Couette flow at Re=1200 (based on the channel half-height and half the velocity difference between the top and bottom plates) is investigated with a spatial domain designed t…
Scattering of swell by currents
Han Wang, Ana B. Villas Bôas, William R. Young +1
The refraction of surface gravity waves by currents leads to spatial modulations in the wave field and, in particular, in the significant wave height. We examine this phenomenon in…
New Exact Betchov-like Relation for the Helicity Flux in Homogeneous Turbulence
Damiano Capocci, Perry L. Johnson, Sean Oughton +2
In homogeneous and isotropic turbulence, the relative contributions of different physical mechanisms to the energy cascade can be quantified by an exact decomposition of the energy…
